Even were the person a virgin with pure morals, there is still conflict of interests. I have to state lack thereof while sending a publication, then think of officials doing deals concerning welfare of nations.

Virginity has nothing to do with political views or ambition or pure morals. You can be a complete arse and still not get laid.

The person you're speaking of has a dubious rep to begin with so the bias against them is already there in full swing. I don't think anyone can enter politics without a conflict of interest at some stage in their careers what they want may not be in the best interest of the nation and yet they'll still push their own agenda.
